John,
Unless you are going to show the car there is a good work around for the condenser. Get a high quality Model A condenser. Elongate the hole on the tab at the end of the Model A condenser so when you slip the condenser into the Model B distributor you can screw it down. Take a short wire and run it from the end of the condenser to where the wire from the Model B condenser attaches. I believe there is a standard Model A wire that is the right length (about 3 inches). PM me if my explaination is not clear.
